here is a pic of the entire sheet but when i dynoed it the guy said not get shift over 4500 cause the motor has 158,000 miles on it lol.
To me it always depended on what gear I was changing to.

Or (in my case) hold until it starts banging& popping,.....then stand harder on the gas hoping it'll go away.I always thought you weren't supposed to lift until you saw Jesus?
The miles wouldn't concern me. It looks like 4800 to 5k would be about right but it is gonna matter where it drops to rpm wise when you shift. You may benefit from a little more time in the upper rpms even though it is not in the peak HP/TQ area so that it drops to a higher rpm that is in your power band when you shift. If that makes sense.
